Here is a really awesome way to use a map to locate a person or their roots taken from the book: A Deck Of Spells, by Professor Charles Porterfield. Using a map, and burning a spiritual incense or tobacco on charcoal in the center, you can use a method similar to Remote Viewing or Dowsing with a deck of cards. You can also do this with a Tarot Deck, as well. The deck used in the photo "For The Seekers," is awesome, because it includes a female / male significator card to represent the person in question.
